I was reading about L2 cache some time ago. Remember I was a bit surprised how much performance you could gain from a large cache.
When you go 64-bit, I don't think you'll feel much different if you do not run a 64-bit os.
I'd advice Windows x64. Check there is all the drivers before you go ahead. I'm running mine with the native mouse driver and it a pain.
When your on x64 things will really improve like moving files. 32-bit is gonna feel like ancient technology for you.
If celeron D the 1st generation 64'er, then I think you'd be better of with a core2duo.
Have fun with it.
